We change all the time, but we resist 'change': we certainly act as if we do not want to add more change to change!

Young people, middle-aged people and older people all believe that they have changed a lot in the past, but would change relatively little in the future! This "end of history" illusion is scientifically proven to be wrong though, in terms of personalities (occupations, habits, traits), core 'values' and 'principles', and preferences (favourite type of music, of vacation, of food, favourite hobby, and the name of one's best friend)!
Circumstances and conditions change (at a non-abating rate), and people consistently show an ability to respond through all ages of life. Resisting change is a recipe for unsatisfactoriness: one way to resist is to take the view that one has figured out how to live one's life, and that this is « the 'best' way given the circumstances » —a form of illusory superiority.

Once a year, many people like to pretend otherwise though, and they make resolutions (usually about changing for the better)… Unsurprisingly, these are rarely kept long.

The ego doesn't want to change, this would implicitly mean relinquishing the idea that it knows itself!
And this would mean that a lot of earlier suffering was self-inflicted (at least in terms of enduring, if not in terms of arising). This is the sort of responsibility hard to take ownership of, in particular after a long denial of it.

Sometimes, the ego doesn't even want to let go of fear; it knows itself as 'afraid' (and maybe calls it 'cautious', just so that it sounds a bit more positive).
But there might be an 'unconditioned' insight, an instant when for no obvious reason some wisdom 'clicks', and you realise that one can move beyond the fear, and it only takes a single moment: it takes the decision not to let fear decide for you! [Even if fear remains present, you no longer relate to it as if you had to give priority to whatever fear says you should do.]
